Posital (www.posital.com) has integrated a bit parallel interface to its range of OCD optical encoders, ensuring a reliable, fast transfer of angular position into higher level controllers. These make them suitable for use in remote regions, as they offer easy diagnosis options that come with simple tools.
The OCD optical encoders are based on a single turn sensor that features a highly Opto-ASIC, which offers a resolution of up to 16 bit per revolution. In addition, a maximum of 14 bit (16384 revolutions) can also be measured by a gear in multi-turn variants. Featuring a code disc built from dimensionally stable, break-proof plastics provides outstanding precision, dynamics and resolution.
Posital’s encoders comply with rigid electromagnetic compatibility requirements, as they feature protective circuits for interface connection and power supply. This enables the encoders to provide reliable operation even under harsh conditions. The encoders’ interface design has been extended to include TTL levels for the data outputs. Seamlessly combined with a vast input voltage range, common for the automation industry, the interface design covers almost all possible applications.
The encoders also feature a push/pull technology that allows it to be connected to standard I/O components from different controller manufacturers. Compatible with open collector variants, the robust encoders offer a protection class of up to IP66.
With suitable couplings or gear wheels, the encoders can be directly integrated into plants and machines. The encoders’ control unit enables users to set its position as well as the preferred zero position in the machine.
